SNMP Trap: Excessive Load
-------------------------

.. _20.1.1|EKB-4115:


Identification

* The originating IP / hostname is used to identify the system generating the traps
* The NMS is responsible for associating traps with each managed system, along with clearing of alarms and escalation to the relevant system operator
* The trap OID is generic  for various SNMP events monitored by the system
* The SNMP system name is included as part of the variable binding to assist identification: 
  ::

    .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone
* The following variable binding can be used to determine that the load average threshold has been exceeded.
  ::
  
    .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotTrigger.0 = ERROR: Excessive load.
* The following variable binding can be used to further diagnose which time interval threshold has been exceeded
  ::

    .iso.org.dod.internet.private.enterprises.ucdavis.laTable.laEntry.laNames.<LoadIdx> = <LoadError>
    .iso.org.dod.internet.private.enterprises.ucdavis.laTable.laEntry.laErrMessage.<LoadIdx> = <LoadMessage>

+-----------------------+-----------+-------------+---------------------------------------+
| Load average interval | <LoadIdx> | <LoadError> | <LoadMessage>                         |
+=======================+===========+=============+=======================================+
| 1 minute              | 1         | Load-1      | 1 min Load Average too high (= 2.52)  |
+-----------------------+-----------+-------------+---------------------------------------+
| 5 minute              | 2         | Load-5      | 5 min Load Average too high (= 1.27)  |
+-----------------------+-----------+-------------+---------------------------------------+
| 15 minute             | 3         | Load-15     | 15 min Load Average too high (= 1.27) |
